CAMRT Radiography Practice Exam

Question: 1 / 1100

What happens to the radiation dose when the distance from a patient to the image intensifier is increased?

It decreases

When the distance from a patient to the image intensifier is increased, the radiation dose actually decreases. This phenomenon occurs because of the inverse square law, which states that the intensity of radiation is inversely proportional to the square of the distance from the source. As distance increases, the amount of radiation reaching the image intensifier diminishes significantly, resulting in a lower dose received by the patient and any nearby personnel.

This principle is crucial in radiography practice as it promotes safety and minimizes patient exposure to radiation. Understanding how distance affects radiation dose can help radiologic technologists and healthcare professionals optimize their techniques, ensuring high-quality imaging while reducing unnecessary radiation exposure.
